Hi SouthernMum,

That's a good question. I tried to look up Winter Springs granite but didn't find it.

What color is it? Uranium is found in true granites which are light in color. So you can rule it out if it's darker.

Either way, I don't think it's a deal killer. You can find scary stories about radioactive granite online but it's not prevalent. I wish I had a definitive answer for you, but it varies with every rock so there's not much I can tell you in absolute terms.

I would definitely not say that granite from Brazil is categorically risky. Brazil is a big place with lots of different rocks. We'd really need more info about the specific rock, rather than a blanket statement.

That said, I'd be interested to see the link where it says that, because I've never heard that before. Also, post a photo of Winter Springs so we can see what it really is.

Hope that helps!
Karin

It says Winter Springs on the slab, and made in Brazil. I love the way it looks!!

Duh,me!!! - it's WHITE SPRING! I don't know why I have such a mental block when it comes to the name of this granite! I went back and checked my photo of the tag on slab. Sorry, Karin! Hope this helps!!

The part on the left is granite pegmatite, so yeah that counts as granite, sure enough. But beyond that I really can't speculate.

Since you asked the original question I've been reading up on this topic, but there's no way to tell what's in a given rock aside from testing it. I know this is not very helpful, sorry! I still don't think I would worry about it though - the risk seems awfully small.

Karin, thank you so much for your help, and for taking the time to read up on this for me! Many, many thanks!

I found some nice research that actually addresses these questions, if you feel like staying up all night reading.
